Copper processing begins with mining copper ore, which contains less than 1% of copper, and ends with sheets of 99.99% pure copper (cathodes). Copper mining generally takes place through open-pit mining, in which a series of stepped benches are dug deeper into the earth. Yet, it can also be mined underground, through horizontal tunnels.

Copper Beneficiation Process . Get A Quote. Introduction . Copper ore is divided into sulfide ore (oxidation rate less than 10%) and oxide ore (oxidation rate greater than 30%) according to the degree of oxidation. Most of the copper produced in the world comes from sulfide ores, and a small part comes from oxidized ores.
